2. Sample Size Used for the Test Set and Data Provenance

The document does not explicitly state a specific "test set" in the traditional sense of a clinical or image-based study. The performance data section refers to "software validation results." This suggests that the testing was primarily focused on the software's functionality, data integrity, and compliance with specifications, rather than a clinical trial with patient data.

• Sample Size for Test Set: Not specified, but likely refers to various data inputs and scenarios used during software validation.
• Data Provenance: Not specified. Given the nature of a software validation for a "Central Station," it's probable that various types of simulated or recorded vital signs data would have been used to test the system's ability to receive, display, and store. It's not a direct patient study with geographical or temporal data provenance.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications

This information is not provided in the document. For a software system like the Central Station, "ground truth" would likely refer to the correctness of the data received, displayed, and stored, and the proper functioning of alerts based on predefined thresholds. The "experts" would likely be software testers, quality assurance personnel, and potentially clinical subject matter experts validating the accuracy of the displayed information against expected results. However, their numbers and specific qualifications are not mentioned.

4. Adjudication Method for the Test Set

This information is not provided in the document. Given that this is a software system for data display and storage, traditional adjudication methods for diagnostic images or clinical outcomes might not directly apply. The "adjudication" would likely be the verification of software outputs against expected behavior, potentially involving multiple testers or a structured review process, but no specific method is detailed.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No, an MRMC comparative effectiveness study was not done. The device is a "Central Station" software system, not an AI-powered diagnostic tool that directly assists human readers in interpreting medical images or making clinical diagnoses. Its function is to display and store vital signs data for review by healthcare professionals.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

The entire study implicitly describes a standalone performance, as the "Central Station" software is the primary subject. The "software validation results demonstrated that the Central Station 3.5 System was in compliance... and that it performed within its specifications and functional requirements for software." This indicates a focus on the algorithm's direct functionality in processing and presenting data. However, it's crucial to understand that while the software operates standalone in processing, its intended use is for review and interpretation by a healthcare professional, meaning it's inherently part of a human-in-the-loop workflow.

7. Type of Ground Truth Used

The ground truth for this device would be defined by the correctness of software functionality and data integrity. This means:

• The system accurately receives data from specified patient monitors.
• The system accurately displays the vital signs parameters and related data.
• The system accurately stores the data.
• System alerts function correctly based on intended logic.
• The software complies with established guidelines and standards.

This is fundamentally a functional and performance validation against predefined software requirements and industry standards, rather than a clinical ground truth like pathology or patient outcomes.

8. Sample Size for the Training Set

This information is not applicable/not provided. The Honeywell HomMed Central Station is described as a software system that receives, displays, and stores vital signs data. It is not an AI/ML device that requires a "training set" in the context of machine learning model development. The software's logic and functionality are likely rule-based or algorithmic, programmed to perform specific tasks, rather than learned from a dataset.

9. How the Ground Truth for the Training Set Was Established

This information is not applicable as there is no "training set" for this type of software device.

This type of submission primarily focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than conducting extensive clinical efficacy trials typically seen for PMA applications.

Here's what can be inferred about the "study" mentioned for this device:

1. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):

   • The document states: "The software validation results demonstrated that the HomMed Central Station System was in compliance with the guidelines and standards referenced in the FDA reviewer's guides and that it performed within its specifications and functional requirements."
   • This indicates a software validation study was performed. However, no specific sample size for a "test set" of patient data is provided. The validation would likely involve testing various scenarios and inputs to ensure the software (Central Station) accurately receives, displays, evaluates, analyzes, and stores the physiological parameters from the HomMed Sentry Patient Monitors.
   • Data provenance is not specified. Given the nature of a software validation, it would likely involve simulated or representative data, potentially from a variety of sources but not explicitly stated. The intent is to process data acquired "within healthcare and home environments."

2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience):

   • The document does not mention the use of experts to establish ground truth for a test set in the context of validating algorithmic performance. The validation appears to be centered on the software's functional correctness and adherence to technical specifications. The "healthcare professional is responsible for the interpretation of the monitored data."

3. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

   • Not applicable/Not mentioned. The study described is a software validation, not a clinical study involving adjudication of interpretations.

4. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

   • No, an MRMC comparative effectiveness study was not done. The HomMed Central Station is described as "a retrospective data view and analysis system" and an "accessory device used by the healthcare professional to display and evaluate the monitored patient data."
